Studies among youth suggest that physical inactivity, sedentary behaviors, and poor diet quality are associated with poor mental health. Few population-based studies have investigated these relationships longitudinally. We examined the association between physical activity, sedentary behaviors, and diet quality in childhood and the incidence of internalizing and externalizing disorders throughout adolescence.
We linked health behavior survey data from 2003 among 10- to 11-year-old children across Nova Scotia, Canada, with administrative health care data from 2003 to 2011. Students' diet quality was assessed using the Harvard Food Frequency Questionnaire. Physical activity and sedentary behaviors were self-reported, and internalizing and externalizing disorders were diagnosed by a physician. We applied Cox regression to examine the associations of the health behaviors with the incidence of internalizing and externalizing disorders between 2003 and 2011.
Of the 4861 participating students, 23.7% and 9.4% had a diagnosis of internalizing and externalizing disorders, respectively. The incidences of internalizing and externalizing disorders were higher among students who were less physically active and spent more time using computers and video games.
These findings suggest that promoting an active lifestyle in childhood may contribute to the prevention of both internalizing and externalizing disorders during adolescence.
青少年研究表明，身体活动不足、久坐行为和不良饮食质量与心理健康不良有关。很少有基于人群的研究对此进行过纵向调查。我们研究了儿童时期的身体活动、久坐行为和饮食质量与整个青春期内化和外化障碍发病率之间的关系。
我们将 2003 年加拿大新斯科舍省 10-11 岁儿童的健康行为调查数据与 2003 年至 2011 年的行政医疗保健数据相联系。使用哈佛食物频率问卷评估学生的饮食质量。身体活动和久坐行为是自我报告的，内化和外化障碍由医生诊断。我们应用 Cox 回归来研究健康行为与 2003 年至 2011 年期间内化和外化障碍发病率之间的关系。
在 4861 名参与的学生中，分别有 23.7%和 9.4%被诊断为内化和外化障碍。身体活动较少和使用计算机和视频游戏时间较长的学生内化和外化障碍的发病率较高。
这些发现表明，在儿童时期促进积极的生活方式可能有助于预防青春期的内化和外化障碍。
